Our recent global market study enabled us to collect information from 1,232 language service providers (LSPs) around the globe (see “The Language Services Market: 2011,” May11). Of these, 17% claimed to offer telephone interpreting. In this brief, we provide more details about where the providers of telephone interpreting services are located throughout the world, how fast they are growing, what has changed since we last wrote about this service (see “The Market for Telephone Interpreting,” Oct10), and what percentage of their revenue is derived from this service.
